Exploring the Properties and Photocatalytic Performance of Ag/AgI/g-C3N4 Composite for Methylene Blue Degradation

Dye pollution from industrial wastewater poses a significant threat to aquatic ecosystems, necessitating efficient removal strategies.Photocatalysis, which employs material such as graphitic carbon nitride (g-C3N4), has emerged as a viable strategy for degrading organic compounds.In this study, visible light active, Ag/AgI/g-C3N4 composite photocatalysts were fabricated via in-situ co-precipitation method with different AgI percent weight loading.Detail characterization was performed utilizing a variety of approaches.The incorporation of Ag/AgI into the g-C3N4 extends the visible light absorption range, contributing to improved photocatalytic activity.The Ag/AgI/g-C3N4 composite outperformed the pristine g-C3N4 in terms of methylene blue degradation.The optimal photocatalytic activity was observed by 1AgI/g-C3N4 photocatalyst with 1% AgI loading, achieving 80% degradation in 5 hours due to the reduced electron-hole recombination and efficient charge transfer between g -C3N4 and Ag/AgI particles.
